WELBOBR CLAY GARNER, OF SEATTLE, GTOH.

warm Emma Application filed December 28, 1822. Serial No. 608,743.

To all whom it may concern:

Be it known that I Wnmorm CLAY GAR- mm, a subject of the king of Great Britain, and now residing at the city of Seattle, in the State of Washington, one of the United States of America, have'invented certain new and useful Improvements in Water Heaters, of which the following is a specification.

This invention relates to improvements in water heaters, and the objects of the invention are to effect increased econom in the transference of heat from the eat source to the water to be heated and, further, to enable the character of the heat source to be changed, if desired.

Further objects are to effect concentration in the application of a heating medium to the water to be heated whereby the speed of heating may be increased. 1

Further objects still are generally to improve and simplify the construction of the device and to better adapt it to perform the functions required of it. 7

And it consists essentially of the imroved construction hereinafter described in detail in the accompanying specification and drawings.

In the drawings:

Figure 1 is a sectional elevation of an embodimentof the invention.

Figure 2 is a cross-section 2-2 ofv Figure 1. I

Figure 3 is an elevation of the heating element.

In the drawings, like characters of reference indicate corresponding parts in all the fi res.

Re rring to the drawings: A indicates the hot water boiler having on the line an intake pipe and an outlet pipe 11.

The side of the boiler may be provided with the usual water glass 12. B indicates the heating element, and one of the features of the, invention lies in the fact that the heating element may be readily replaced and gas may-be substituted for electricity or other heating means.

I have illustrated a form of electrical heating element including a core 13 .having a cylindrical portion 15, the electric heating resistance being wound upon the spiral ves 16 in the usual manner and connected to terminal conductors 17 an 18 which lead to cords 19 and a plug cockat 20.

'32 and unscrewing the thread The cylindrical portion 14 is aboutonethird of the height of the heating element and is formed with a plurality of concaved reflecting surfaces 21, from which'the heat is designed/to be reflected as hereinafter described, the said reflecting surfaces being covered with a metal reflecting member 22 secured to or forming part of the base 23 which supports the core 13, and itself rests upon the bottom plate 24 of the boiler, the said bottom plate having an outlet conduit or neck 25 through which the cord 19 passes.

The core 13 fits closely to a casing 26 of similar shape to the core, and having a vent pipe 27 at the top thereof which leads through the top of the boiler and is nor-- mally closed by a screw-threaded cap 28;

The water to be heated is designed to circulate on the outside of the casing 26 being guided by a spiral bafile 28 which extends between the casing 26 and a second enclosing casing 29, the upper end of which is provided with a relatively large screwthreaded neck 30 which has screwthreaded engagement with the to plate 31 of a supporting member 32 o conoidal shape, the lower extremities of which are connected to the bottom of the boiler as by means of bolts32 which pass through the side wall 33 of the "boiler as well as through flanges 34 and 35 formed on the member 32 and the bottom plate 24 respectively;

The space between the members 29 and 32 is filled with air and is desi ed to form heat insulation, The heating circuit for the which extends from the outlet 11 to a T- union 36' from which a pipe 37 leads to-an elbow 38 connected to the inlet conduit 39 which 0 ns in the water heating chamber 40 constltuted by the space between the cas ings 26 and 29. The water being forcedto pass by the bafile 28 in a spiral manner around the heating element B is heated thereby and passes out through the neck 30 into the boiler. The water to be drawn ofi from the boiler is drawn through a conduit 41 connected to the union 36' and the said union preferably including a check valve which prevents withdrawal of the water from ;he heating chamber 40 through the pr 3 It: will be seen that, by loosenin thebolts neck" 30, the heatin element as a whole may be removed an furthermore, that the member 'water boiler is completed by a conduit 36 B may be readily removed from the interior of the casings 26 and 29, and, when this is done, any alternative form of heating means might be laced within the casing 26.

The re ectors 22 will cause reflecting of heat from the cylindrical portion of the core B to the inner side of the surface of the casing 26 over the outer surface of which the water to be heated passes. I

It will be further observed that the whole heating element is within the boiler A. The heater may be used for heating water or other fluids or for makin steam.

As many changes coufd be made in the above construction and many apparently widely different embodiments of my invention within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying drawings and specification shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

1. A water heater comprising a boiler, a tapered supporting member on the bottom of the boiler, a tapered casing supported from the supporting member being spaced therefrom by an air space, and a heating element within the casing.

2. A water heater comprising a boiler, a tapered su porting member on the bottom of the boi er, a tapered casing supported from the supporting member being spaced therefrom by an air space, a heating element within the casing, a water chamber between the casing and the heating element, and means for causing circulation of water from the boiler through the water chamber.

' 3. A water heater com rising a boiler, a tapered su porting mem r on the bottom of the boi er, a tapered casing supported from the supporting member being spaced therefrom by an air space, a heating element within the casing, a water'chamber between the casing and the heating element, means for causing circulationof water from the, boiler through the water chamber, and. a spiral bafile in the said water chamber.

4. In a water heater, a heating element comprising a cylindrical portion having reflecting sections and a spiral portion, an electrical resistance on the spira portion, a water heating casing surrounding the heating element, and means for circulating water in the water heating casing.

5. A water heater of the character de". scribed comprising a boiler having side walls and a removable bottom conical supporting member secured to the side walls of the boiler having a threaded top plate, a casing having a threaded neck engaged with the top plate and having its body portion separated therefrom, a second casing within the first casing spaced therefrom to constitute a water heating chamber, heating means within the second mentioned casing, and

means for circulating water in the water surfaces, and a conical portion-having elec-.

trical resistance thereon.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
